. APPARATUS FOR FEEDING- AND SEWING FILLED SACKS.

Application filed January 6, 1910. Serial No. 536,765H

To all whom it may concern:

Be it known that I, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Oak Park, in the county of Cook, State of Illinois, have invented certain new and use ful Improvements in Apparatus for Feeding and Sewing Filled Sacks, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

My invention relates to an organized apparatus for feeding and sewing filled sacks, and in general is of the type known as the Union Special filled bag sewing apparatus, as embodied generically in'patent of Bigelow, No. 875,311, of December 31st, 1907, and more specifically in patent of Foster, No. 875,339 of December 31st, 1907. In

brief, and without enumeration of detail,

this type of apparatus embodies a supporting framework, an adjustable table over which runs a conveyor belt for the filled bags, which conveyer belt delivers the bags successively to a stitch-forming mechanism which overhangs the edge of the framework. After the sewing of the mouth of a bag has been performed, the chain of stitching between it and the succeeding bag is severed by a cutting mechanism, of which any one of various types may be employed. The

conveyer belt is adjustable up and down to accommodate varying sizes'of bags, this adjustment being effected without varying the operative connections which drive the conveyer belt and the stitch-forming mechanism. This type of machine includes also a guiding rail for the body of the bag to rest against in order that it may accurately register with and be fed to the stitch-forming mechanism.

With this general statement as to the typeof machine at present in use, it may be stated that the present invention has for its object to improve the mechanical structure of such apparatus with the idea of securing greater nicety of adjustment, greater facility of handling, and increased production.

The invention, therefore, consists, first, in the provision of an adjustment of the sewing machine head carrying the stitch-forming mechanism, whereby within certain ranges of bag sizes, such adjustment will sufiice without making use of the more ex- Specification of Letters Patent.

Patented nee. as, rare.

tensive range of adjustment permitteEQ conveyer.

Secondly, the invention consists in com bining with the cutting apparatus for sever-' ing the chain of stitches, means for causing the bag after it has passed the stitch-forming mechanism, to be operated to draw the chain of stitching between it and the next bag taut, and laterally into the line of the severing device, to enable the latter to more efiectually sever the threads.

Thirdly, for the purpose just above mentioned, it consists in providing two guide rails in difi'erent vertical planes, cooperating v with a tilter boa-rd beneath the conveyer belt, whereby when the bag leaves the first guide rail, it will be tilted laterally against the rear guide rail, and thus draw the chain of stitching taut, and into the line of action of the severing device.

Finally, the invention consists in the various details of construction and arrangements of parts. whereby the results aimed at are accomplished in a simple and practical manner.

The invention is illustrated in the accompanying drawings, in which a Figure 1 is a front left hand perspective view of an organized filled bag sewing apparatus embodying my invention; Fig. 2 is a side view of the same, with various parts removed; Fig. 3 is a left hand perspective of the sewing head supporting bracket, with the guide rails, with the sewing head removed; Fig. 4 is aright hand perspective view, similar to Fig. 3; Fig. 5 IS a plan view of Fig. 3;.Fig. 6 is a detail section on line 66, of Fig. 3; Figs. 7 and 7 are front and side views of the cutting or severing mechanism; Fig. 7 is a detail view of the presser foot; Fig. 8 is a left hand perspecherein shown for cutting or severing the chain of stitches between two consecutive bags So far, however, as the particular cutting or severing mechanism, with its cooperative arrangement and relation to the sewing machine feeding mechanism is concerned, I do not herein claim it, as it forms the subject matter of an application filed by me of even date herewith, Serial No. 536,766. It is only herein illustrated as a suitable form of severing mechanism, and one which lends itself to cooperation with the means devised by me to cause the bag after it has been sewed, to shift to such position that the chain of stitching will be stretched taut and drawn into position where' the special form of severing device will be effective. Furthermore, I do not claim herein either broadly or specifically, a means for shifting the position of the bag after the mouth thereof has been stitched, to draw the chain taut that a cutting or severing device may more readily clip it off, as that is not of my invention, the latter as above stated, so far as this point is concerned, residing in the means for shifting the bag, not only to draw the chain of stitching taut, but to draw it laterally into the path of action of my special form of severing device.

Referring now to the drawings, the supporting framework A is of the usual iron construction, having its legs provided with caster wheels. The conveyer belt B, the means for driving and supporting the conveyer belt, the sliding worm gear,-the worm wheel, and various other parts, are similar in general construction and mode of operation to thecorresponding features shown in the Foster patent above referred to; the con veyer and its supporting table C, being similar to that shown in the Bigelow patent referred. to. Certain changes, however, have been herein embodied, which may be mentioned.

The vertical shaft D is driven by the electric motor E,'carried by the framework. It is j ournaled in bearings at the base and top of the framework. It extends above the top of the framework, and drives the belt pulley a, belted to theusual belt pulley b of the sewing machine. This vertical shaft D carries below the top of the framework the worm wheel splined on it, and engaging the worm gear, on the shaft with the sprocket gear 0 which has a sprocket chain connection with one of the conveyer belt pulleys. A usual foot-actuated clutchmechanism is used for starting and stopping the movement of the shaft D. j

The bracket carrying the conveyer belt pulleys, has guiding ways on the front legs of the framework, and the entire conveyer belt mechanism is raised or lowered by means of screw shafts F, engaging the bracket, carrying at their upper ends horizontal beveled gears 01, meshing with vertical beveled gears e on the hand crank shaft f. By this construction,'it will be seen that a simple arrangement is provided for raising and lowering the conveyer belt to accommodate sacks of varying heights. This adj ustment of the conveyer belt is necessary in an apparatus designed to operate upon bags of practically all sizes, because it permits a wide range of adjustment. It frequently happens, however, that after the approxi-' mate adjustment of the'conveyer for bags of certain size has been accomplished, by raising or lowering the said conveyer, a somewhat greater degree of nicety is required in the location of the line of stitching by slot j and screw is adjustment, the ma-.

chine bracket J, formed with the pad upon which the sewing machine base or standard is supported.

The bracket I has a projecting arm m sleeved uponthe vertical shaft D, and has bolted to it a plate K to which is secured the bolt n, to which is pivoted one end of a link 0 pivoted at its opposite end to the hand 1ever L, which passes through a slit in the web g, and is pivoted to the inside of the standard G.

It will be seen that by manipulation of the leverL, the bracket I and with it the machine-supporting bracket J is moved up and down, and the height of the sewing machine thus adjusted.

The bracket I may be clamped in any posewing head permits the stitching point of the sewing head to be shifted transversely of the filled bag being stitched, so as to bring the stitching point centrally over the filled bag. If the bag is of greater width than the conveyer, the mouth of the bag is oifset from the center line of the conveyer, but by means of this adjustment, the sewing head may be shifted and the stitching point brought-centrally over the bag, and at the same time the needle always reciprocates in a horizontal plane for'variousadjusted positions of the sewing head. Extending downward from the bracket plate K is an angle arm Q, to which is adjustably bolted the bracket 32, to the lower arm of which is adjustably secured the guiding rail for the filled bag. Adjustment of the guiding rail transversely of the conveyer is permitted, by reason of the adjustment of the bracket 79, upon the arm Q, and adjustment longitudinally of the conveyer belt is permitted by the screws 9 and longitudinal slot 1'. It will thus be seen that as the sewing machine head is adjusted, the guiding rail R is also adjusted vertically, and as before stated, this adjustment of sewing machine head may be all that it necessary for use on an apparatus of this character, if there is no great disparity in the sizes of bags to be sewed, but even if there is such disparity, this adjustment of the head permits of a greater degree of nicety of adjustment of the sewingvmechanism with respect to the mouth of the bag, than if only the adjustment of the conveyer belt were made use of.

- The sewing machine has attached to it a vertical thread guide Y.

The guiding rail R terminates preferably a short distance in rear of the stitching mechanism, and is substantially in such a line that it guides the mouth of the bag properly to the stitching mechanism. In rear of the guiding rail R in the direction of feed of the conveyer,'and in a vertical plane behind the said rail R, is a second guiding rail S, vertically adjustable by the screw and slot 25, adjustment, on the bracket T, which bracket is horizontally adjustable by means of hand screws u on the top of the supporting framework. It will be understood that these two guiding rails form, in efiect, a two-part rail, of which one part guides the bag up to the stitching mechanism, and the other part guides the bag after it leaves the stitching mechanisms Between the top of the conveyer belt B and its supporting table C is placed a board U, which inclines downwardly and rear wardly ata point about beneath the stitching mechanism, the purpose of such being that when a bag mouth has been stitched, the weight of the bag as it leaves the substantially level part of the board U will cause it to tilt forwardly and sidewise against the guide rail S, or in other words, to topple over against the guide rail S, thus drawing taut the chain of stitching and drawing it also into the path of action of a cutting or severing mechanism, which, per 86, forms no part of the present invention as hereinbefore stated. This severing mechanism is shown in Fig. 7, and briefly, embodies a movable cutting blade 1, operated from the feed-operating devices of the machine, cooperating with a stationary blade 2, and operating to sever the chain of stitching at a point back of the rear feed dog 3,

which is split centrally, as is also the cooperating part of the presser foot 4, to allow the bag in its toppling over movement to draw the chain of stitching between the two parts of the rear feed dog, and thus into the line of movement of the cutting blade 1.

From the above it will be notedthat the severing members 1 and 2 are located in the rear of the plane of travel of the mouth of the bag being stitched which is engaged by the feed dog 3. being operated by the feed operating devices of the machine move continuously. Said severing devices as clearly shown in Fig. 7 have a receiving throat which opens toward the plane of travel of the mouth of the bag being stitched which passes across the work support of the sewing machine and is engaged, as above noted by the feed dog 3. WVhen the bag is tilted rearwardly, the connecting chain of stitches between the stitched bag and the sewing mechanism will be carried into the receiving throat of the severing devices.

While, as before stated, I make no claim herein to the cutting mechanism per 86, the same being claimed in my application above referred to; nor broadly to the providing of means to tilt or topple the bag after the These severing members stitching has been performed to automatically tighten the chain of stitching to render the severing action thereon more effective, as that is the invention of another party; nevertheless, in addition to the various details looking to the making of a better and more effective apparatus for the purpose of sewing filled bags, I believe I am the first to provide means for feeding and sewing themouth of a filled bag, and after the sewing has been accomplished, to shift the bag laterally to tighten the chain of stitching, and at the same time draw it into the line of action of a severing device.
